Textured cover assemblies for electronic devices are disclosed. The textured cover assemblies may provide a combination of optical and tactile properties to the electronic devices. In some cases, a textured cover assembly may be provided over decorative coating.

A method for producing a decorative panel, appearing and/or feeling like a machined metal, including taking a glass substrate, including at least one first surface; and one or more solid metal films, made of one or more metal(s) or metal alloy(s); generating a pulsed LASER beam; directing a metal deposition on at least the first surface, disposing the one or more metal film(s) facing the at least first surface, between the substrate and the LASER source, and applying the LASER beam on the one or more metal film(s) transferring the one or more metal(s) or metal alloy(s) onto the at least first surface, forming a coating including a metal layer covering all or part of the at least first surface, the metal layer including a top surface; and surfacing the metal coating top surface to alter the surface condition giving it the appearance and/or feel of a machined metal.

The present invention relates to silicon coated metal microparticles in which at least a part of a surface of a metal microparticle composed of at least one of metal elements or metalloid elements is coated with silicon, wherein the silicon coated metal microparticles are a product obtained by a reduction treatment of silicon compound coated precursor microparticles in which at least a part of a surface of a precursor microparticle containing a precursor of the metal microparticles is coated with a silicon compound, or silicon doped precursor microparticles containing a precursor of the metal microparticles. Because it is possible particularly to strictly control a particle diameter of the silicon compound coated metal microparticle by controlling conditions of the reduction treatment, design of a more appropriate composition can become facilitated, compared with a conventional composition, in terms of diversified usages and desired properties of silicon compound coated metal microparticles.

A substrate coated on one of its faces with a stack of thin layers having reflection properties in the infrared and/or in solar radiation, including two metallic functional layers, in particular on the basis of silver. Each of the metallic functional layers is disposed between two dielectric coatings. The coating includes at least two absorbent layers which absorb solar radiation in the visible part of the spectrum, which is disposed at least in two different dielectric coatings.

An electronic device may include electrical components and other components mounted within a housing. The device may have a display on a front face of the device and may have a glass layer that forms part of the housing on a rear face of the device. The glass layer and other glass structures in the electronic device may be provided with coatings. An interior coating on a glass layer may include multiple layers of material such as an adhesion promotion layer, thin-film layers of materials such as silicon, niobium oxide and other metal oxides, and metals to help adjust the appearance of the coating. A metal layer may be formed on top of the coating to serve as an environmental protection layer and opacity enhancement layer. In some configurations, the coating may include four layers.

Glass elements are provided that include a coating and a sheet-like glass substrate. The sheet-like glass substrate has a first surface and a second surface opposite the first surface. The coating is disposed in at least some areas of at least one of the first and second surfaces. The coating is an inorganic glass-based coating that includes at least one glassy component; at least one pigment comprising pigment particles; and a filler. The filler is inorganic and includes filler particles with a d.sub.50 value, based on an equivalent diameter, of at least 0.1 μm and less than 10 μm.

A final layer of a multi-layer of thin deposit and lacquer layers of a decorative faceted functional stone formed by 10 to 35% of nano/colloidal silica, optionally nano/colloidal alumina, 30 to 50% of encapsulated aluminium flakes in grain size of 15-80 μm, 2 to 10% of Fe3O4 in grain size of 3-50 μm, and 10 to 40% of polyisocyanate-hardened mixture of epoxy and polyether resin, and a method for increasing the opacity and hardness of a multi-layer of thin deposit and lacquer layers of a decorative faceted functional stone by applying this final layer.

Electronic devices including a textured component such as a cover member positioned over one or more components of the electronic device. Different surface regions of the textured component may be textured differently in order to provide optical contrast. For example, differently textured surface regions may differ in gloss, translucency, or both. In some cases the cover member defines a protruding feature and a surface region of the protruding feature is textured differently than an adjacent surface region.

A printable ink mixture may include: a medium, orthophosphoric acid, at least one metal oxide, and at least one pigment. A method for producing a color print on a glass or ceramic surface may include: producing an ink mixture including a medium, orthophosphoric acid, at least one metal oxide, and at least one pigment, applying the ink mixture to the glass or ceramic surface, removing the medium from the ink mixture, and baking the ink mixture on the glass or ceramic surface to produce the color print.

A film having a metallic luster that is easier to manufacture and exhibits little degradation over time, an article having the film formed thereon, and a manufacturing method for the film having a metallic luster. The film, which has a metallic luster, is characterized by containing a thiophene polymer. The manufacturing method for the film which has a metallic luster is characterized by a thiophene being polymerized using an oxidizing agent and made into a solution containing the thiophene polymer, and then coating and drying the solution containing the thiophene polymer on an article. The article having the film, which has a metallic luster formed thereon, is characterized by containing a thiophene polymer.
